Hi. It seems that PPS mapping can be used only once.
I have following two pins:
PPS_Mapping(0, _OUTPUT, _U1TX);
PPS_Mapping(4, _INPUT, _INT1);
Depending on which line comes first, I get either working INT1 or Uart tx, but not both.
Played also with the IOLOCK one-way bit but no help.
Any ideas?
EDIT:
Got it working like this, but still it seems like a bug that oneway config bit does not work as intended.
Unlock_IOLOCK();
PPS_Mapping_NoLock(4, _INPUT, _INT1);
PPS_Mapping_NoLock(0, _OUTPUT, _U1TX);
PPS_Mapping_NoLock(1, _INPUT, _U1RX);
Lock_IOLOCK();
PPS mapping can be used only once on PIC24FJ16GA002

Hi,
Did you disable IOLOCK protection bit in the Edit Project settings?
Kind regards,

Hi,
Unfortunately, I do not have this MCU to test it, but it sounds like the IOL1WAY bit from the CW2: FLASH CONFIGURATION WORD 2 register has set to 1.
When you load the hex file in the mikroProg Suite, there is a config bit "IOLOCK Bit One-Way Set Enable Bit", how has this bit set in both cases?
This bit should be set as "The OSCCON <IOLOCK> bit can be set and cleared as needed".
Kind regards,
